I completely agree that the Pacific ocean is the driver for the NA climate.Are you telling me that a Polar Vortex isn't due to the warm water in the Pacific? Hmmm, I'd think you'd know that, like it is responsible for an EL Nino. Right? Hmmm how does it do that and which way does it force the winds to blow?I blathered on your blather!
But since I made no comment whatsoever wrt to the things about which you posted, How have I blathered? On the other hand, in your post above, you blathered:
"the convection system that starts with the Pacific Ocean has to go over and through the NA continent when the wind blows". Pacific ocean convection does not and never has "go(ne) over to and through the NA continent. The Pacific currents are flows of water while the NA continent is a CONTINENT composed of crustal ROCK. Duh. Secondly, yes NA is about 4% of the Earth's surface, while the Pacific ocean surface represents about 32% of the Earth's surface. Get it?
You said "the convection system that starts with the Pacific Ocean", and so I naturally assumed you were referring to ocean currents. If you wanted to discuss the Polar Vortex, perhaps you should have been more specific. But more to the point, you seemed to be arguing that North America, which, by your own admission plays a larger role in global warming than some here will admit while simultaneously downplaying the role of the Pacific. And then you seem to reverse your argument. What's up with that? Perhaps you should rephrase your argument so that it actually makes sense.
But I will admit that North America does play a large role in AGW, since that is where a huge percentage of the manmade ghgs originate.
It isn't the only driver. In the Eastern U.S., at least, there are many drivers, not the least of which are the Gulf of Mexico, Canadian/Arctic fronts, and the Atlantic Ocean. And lets not forget lake effects (I.e., referring to how the Great lakes affects the Midwest climate).
Very good! Nowhere do you mention man as a proximal cause. Maybe you're finally learning something!
